(10 points) Question 9 Multiple Choice (round radio buttons) Level of measurement associated with "floating zero" nominal ordinal interval ratio Question 10 Multiple Choice (round radio buttons] (10 points) Level of measurement associated with "absolute zero nominal ordinal _interval ratio Question 11 Multiple Answer (square checkboxes) (5 points) Checkmark all the statements that can be made about this scenario. A researcher is interested in the difference between younger females' and older females' attitudes about having annual mammograms. She intends to use a Likert scale survey. She randomly selects 50 females under 45 years of age and randomly selects 50 females age 45 or older. Observational research Experimental research IV = grouping by age DV = grouping by age DV = attitudes 2 groups of females are related 2 groups of females are independent DV is measured at nominal level DV is measured at interval level Study is looking for a difference between 2 groups Study is looking for a correlation between attitude and gender

Answer 1

Answer: Interval

( The interval data involves the differences between the measures but there is no true zero.)

Answer: Ratio.

( The level of measurement associated with absolute zero is the ratio. In this measurement true zero that means absolute zero exists.)

Answer: Experimental research.

( This is because the researcher wants to study the attitude towards the particular subject or examining process that the female of different ages have.)
